On some days, usually when her back or legs hurt or feel very weak my mom walks in a terribly hunched / slouched way with her 4 wheeled rollator. (It appears as if the walker is too far from her body when this happens.) On these days it is difficult for the aide to help support her when walking. We took her to get fitted for a good pair of quality walking shoes. The salesman suggested that we lower the back legs of the rollator one notch so that it would "force" her to walk straighter. Has anyone heard of this approach? It is straining the aide's back to assist her. The primary care doctor suggested putting off the wheelchair until it is completely necessary. (Now we only use it for occasional doc appts.) Does this mean it is time for the wheelchair?
